Just going over an old report by Burzynski, (from the reference list) and thought I'd share this fun tidbit. May explain why the Blackhawk bulk samples were so incredible (10.6g/t)..they cherry picked a couple veins they stumbled across. Too bad they are gone and we can't use them! Here's the link...

The work by Blackhawk in the early 1960’s was the second major period of activity at the

Bellechasse deposit and created the second major staking rush in the Bellechasse area.

Blackhawk conducted test geophysical surveys, including magnetics, EM and resistivity

(the EM and resistivity were deemed to be inconclusive and ineffective while the MAG was

believed useful in delineating the contacts of the gabbro and sediments), and also did

some local stripping and trenching on lot 11 in the early part of 1960. A drilling campaign

was planned but abandoned when the first drill site was being cleared and a large vein (the discovery” or No. 1 Blackhawk vein) carrying “free gold in considerable quantity” (Blair,1960d) was discovered. Blackhawk then proceeded to strip and trench seven areas along strike, uncovering a second major vein (the “sulphide” or No. 2 Blackhawk vein, known recently as the “Rico” vein) in the process. The two veins were reported as being approximately 250 feet (76m) in length and generally greater than seven feet (2m) wide.

Individual bulk samples ranging up to almost nine short tons were taken from some of the

pits. Nearly all returned high grade gold values. Following the bulk sampling, Blackhawk

commenced their drill program, which consisted of 13 holes totaling 3,311 feet (1,009m) on

lots 10 and 11, Range III. H.J. Bergmann, consulting mining engineer to Blackhawk, was

the first to recognize there was a sampling difficulty associated with the Bellechasse

deposit. In a letter to the directors (Bergmann, 1960c) he noted:

“The gold in (the) vein(s) is largely in the free state and is not associated with sulphides

although there are minor amounts of sphalerite with associated gold. Bulk sampling is thus

the most accurate method of sampling the vein(s) as both channel and diamond drilling

tend to give erratic results.”
